Permanent Magnet Arrangement for Generator Rotor - An electric generator rotor having one or more permanent magnets coupled thereon. The permanent magnets provide a constant magnetic field in the rotor at all times, therein minimizing the effect of rotor residual magnetism on the start-up characteristics of the electric generator. The type and placement of the one or more permanent magnets on the rotor and/or magnetic field confinement techniques may be utilized to control spatial distribution of magnetic field within the rotor.
